Abstract
The invention discloses a slit type air ring, which comprises a body and a distribution plate, wherein the distribution plate is provided with a plurality of evenly distributed small holes; the interior of the body is provided with an annular cavity, one end of the body is provided with air inlets communicating with the annular cavity, the other end of the body is provided with an annular slit opening communicating with the annular cavity, the distribution plate is arranged in the annular cavity, the sidewall of the distribution plate is in tight contact with the sidewall of the annular cavity, and the axis of the distribution plate is superposed with the axis of the annular slit opening. Air enters the annular cavity from the air inlets of the slit type air ring; since the distribution plate is arranged in the annular cavity and the walls of the distribution plate and the annular cavity are in tight contact, the air entering the annular cavity runs through the small holes in the distribution plate; moreover, since the small holes in the distribution plate are evenly formed, the airflow is homogenized by the distribution plate, at the moment, the homogenized airflow passes through the small holes of the distribution plate and is uniformly jetted out from the annular slit opening, and thereby the stability of the airflow is realized.
Description
Technical field
The present invention relates to a kind of vane, more particularly, to a kind of slit vane.
Background technology
Vane is widely used in the fields such as weaving, refractory ceramic fibre, glass fibre, be apply in commercial production more
A kind of construction package.Taking ceramic fibre production process as a example, vane is generally supported the use with the wire swaying roller of column type, is placed in and gets rid of silk
Roller rear end, after stream stock forms fiber in the presence of wire swaying roller, fiber is carried out secondary drawing-off by the high velocity air that vane produces,
Make distribution of fiber diameters more uniform, shot content reduces.
At present, vane, typically by having multiple annular steel pipes into and out of air port or annular housing is made, leads to into and out of air port
Cross and punch or inlay nozzle realization on annular steel pipe or annular housing, air outlet mostly is circular hole structure and sharp-mouth type structure.
Due to cavernous structure or the sharp-mouth type structure of air outlet, therefore, wind is from each hole or in nozzle with shapes such as column, fan-shapeds
Formula flows out and moment dissipates, and air-flow is more and interfering property strong, and air-flow is uneven, do not concentrate, and then leads to fiber fibre forming property
Can be poor.
Additionally, the manufacture of annular steel pipe and annular housing is more difficult, special process is needed to process.
Content of the invention
In view of this, it is an object of the invention to provide a kind of slit vane, the air outlet of vane is made to spray with realization
The uniform purpose of air-flow.
To achieve these goals, the invention provides following scheme:
A kind of slit vane, including body and distribution plate, described distribution plate has multiple apertures being evenly distributed；

On the first side wall, the outer end of described distribution plate is stuck in the second sidewall of described exogenous wind ring assemblies, and the of described endogenous wind ring assemblies
Form narrow annular channel mouth between 4th side wall of three side walls and described exogenous wind ring assemblies.
Preferably, in above-mentioned slit vane, described exogenous wind ring assemblies and described endogenous wind ring assemblies are bolted.
Preferably, in above-mentioned slit vane, the slit width of described narrow annular channel mouth is 0.5～5mm.
Preferably, in above-mentioned slit vane, described narrow annular channel mouth is had down with the connection end of described toroidal cavity
Angle, and larger one end in cross section of described chamfering and described toroidal cavity connect, less one end in cross section of described chamfering
Connect with described narrow annular channel mouth.
Preferably, in above-mentioned slit vane, the aperture of described distribution plate a diameter of
Preferably, in above-mentioned slit vane, the cross-sectional area of described air inlet: have on described distribution plate is multiple
The cross-sectional area sum of aperture: the cross-sectional area of described narrow annular channel mouth=(3～2): (2～1.5): 1.
Preferably, in above-mentioned slit vane, the number of described air inlet is 2, and 2 described air inlets are with regard to described
The axle center of slit vane is symmetrical.
Preferably, in above-mentioned slit vane, the cross section of described air inlet is circle.
It can be seen from above-mentioned technical scheme that, the slit vane that the present invention provides, including body and distribution plate, distributes
Multiple apertures being evenly distributed are had on plate；Wherein, the inside of body has toroidal cavity, and one end of body has connection annular
The air inlet of cavity, the other end of body has the narrow annular channel mouth of connection toroidal cavity, and distribution plate is arranged in toroidal cavity,
The side wall of the side wall of distribution plate and toroidal cavity fits tightly.Wind enters toroidal cavity from the air inlet of slit vane, due to
Distribution plate is arranged in toroidal cavity, and the side wall of distribution plate and the side wall of toroidal cavity fit tightly, and therefore, enters toroidal cavity
Wind pass through aperture on distribution plate, and due to the multiple apertures arrangement that has on distribution plate uniformly, therefore, distribution plate is to air-flow
Carry out homogenizing, now, air-flow after homogenizing sprays it is achieved that air-flow through the aperture of distribution plate from narrow annular channel mouth is uniform
Stablize.
